| CVE-2021-32675 | 5 Debian, Fedoraproject, Netapp and 2 more | 6 Debian Linux, Fedora, Management Services For Element Software and 3 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| Redis is an open source, in-memory database that persists on disk. When parsing an incoming Redis Standard Protocol (RESP) request, Redis allocates memory according to user-specified values which determine the number of elements (in the multi-bulk header) and size of each element (in the bulk header). An attacker delivering specially crafted requests over multiple connections can cause the server to allocate significant amount of memory. Because the same parsing mechanism is used to handle authentication requests, this vulnerability can also be exploited by unauthenticated users. The problem is fixed in Redis versions 6.2.6, 6.0.16 and 5.0.14. An additional workaround to mitigate this problem without patching the redis-server executable is to block access to prevent unauthenticated users from connecting to Redis. This can be done in different ways: Using network access control tools like firewalls, iptables, security groups, etc. or Enabling TLS and requiring users to authenticate using client side certificates. | |||||
| CVE-2021-32672 | 6 Debian, Fedoraproject, Netapp and 3 more | 8 Debian Linux, Fedora, Management Services For Element Software and 5 more | 2024-11-21 | 4.0 MEDIUM | 5.3 MEDIUM |
| Redis is an open source, in-memory database that persists on disk. When using the Redis Lua Debugger, users can send malformed requests that cause the debugger’s protocol parser to read data beyond the actual buffer. This issue affects all versions of Redis with Lua debugging support (3.2 or newer). The problem is fixed in versions 6.2.6, 6.0.16 and 5.0.14. | |||||
| CVE-2021-32642 | 2 Fedoraproject, Uninett | 2 Fedora, Radsecproxy | 2024-11-21 | 7.5 HIGH | 7.0 HIGH |
| radsecproxy is a generic RADIUS proxy that supports both UDP and TLS (RadSec) RADIUS transports. Missing input validation in radsecproxy's `naptr-eduroam.sh` and `radsec-dynsrv.sh` scripts can lead to configuration injection via crafted radsec peer discovery DNS records. Users are subject to Information disclosure, Denial of Service, Redirection of Radius connection to a non-authenticated server leading to non-authenticated network access. Updated example scripts are available in the master branch and 1.9 release. Note that the scripts are not part of the installation package and are not updated automatically. If you are using the examples, you have to update them manually. The dyndisc scripts work independently of the radsecproxy code. The updated scripts can be used with any version of radsecproxy. | |||||
| CVE-2021-32628 | 5 Debian, Fedoraproject, Netapp and 2 more | 6 Debian Linux, Fedora, Management Services For Element Software and 3 more | 2024-11-21 | 6.0 MEDIUM | 7.5 HIGH |
| Redis is an open source, in-memory database that persists on disk. An integer overflow bug in the ziplist data structure used by all versions of Redis can be exploited to corrupt the heap and potentially result with remote code execution. The vulnerability involves modifying the default ziplist configuration parameters (hash-max-ziplist-entries, hash-max-ziplist-value, zset-max-ziplist-entries or zset-max-ziplist-value) to a very large value, and then constructing specially crafted commands to create very large ziplists. The problem is fixed in Redis versions 6.2.6, 6.0.16, 5.0.14. An additional workaround to mitigate the problem without patching the redis-server executable is to prevent users from modifying the above configuration parameters. This can be done using ACL to restrict unprivileged users from using the CONFIG SET command. | |||||
| CVE-2021-32627 | 5 Debian, Fedoraproject, Netapp and 2 more | 6 Debian Linux, Fedora, Management Services For Element Software and 3 more | 2024-11-21 | 6.0 MEDIUM | 7.5 HIGH |
| Redis is an open source, in-memory database that persists on disk. In affected versions an integer overflow bug in Redis can be exploited to corrupt the heap and potentially result with remote code execution. The vulnerability involves changing the default proto-max-bulk-len and client-query-buffer-limit configuration parameters to very large values and constructing specially crafted very large stream elements. The problem is fixed in Redis 6.2.6, 6.0.16 and 5.0.14. For users unable to upgrade an additional workaround to mitigate the problem without patching the redis-server executable is to prevent users from modifying the proto-max-bulk-len configuration parameter. This can be done using ACL to restrict unprivileged users from using the CONFIG SET command. | |||||
| CVE-2021-32626 | 5 Debian, Fedoraproject, Netapp and 2 more | 6 Debian Linux, Fedora, Management Services For Element Software and 3 more | 2024-11-21 | 6.5 MEDIUM | 7.5 HIGH |
| Redis is an open source, in-memory database that persists on disk. In affected versions specially crafted Lua scripts executing in Redis can cause the heap-based Lua stack to be overflowed, due to incomplete checks for this condition. This can result with heap corruption and potentially remote code execution. This problem exists in all versions of Redis with Lua scripting support, starting from 2.6. The problem is fixed in versions 6.2.6, 6.0.16 and 5.0.14. For users unable to update an additional workaround to mitigate the problem without patching the redis-server executable is to prevent users from executing Lua scripts. This can be done using ACL to restrict EVAL and EVALSHA commands. | |||||
| CVE-2021-32625 | 2 Fedoraproject, Redislabs | 2 Fedora, Redis | 2024-11-21 | 6.5 MEDIUM | 7.5 HIGH |
| Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache, and message broker. An integer overflow bug in Redis version 6.0 or newer, could be exploited using the STRALGO LCS command to corrupt the heap and potentially result with remote code execution. This is a result of an incomplete fix by CVE-2021-29477. The problem is fixed in version 6.2.4 and 6.0.14. An additional workaround to mitigate the problem without patching the redis-server executable is to use ACL configuration to prevent clients from using the STRALGO LCS command. On 64 bit systems which have the fixes of CVE-2021-29477 (6.2.3 or 6.0.13), it is sufficient to make sure that the proto-max-bulk-len config parameter is smaller than 2GB (default is 512MB). | |||||
| CVE-2021-32617 | 2 Exiv2, Fedoraproject | 2 Exiv2, Fedora | 2024-11-21 | 4.3 MEDIUM | 4.7 MEDIUM |
| Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. An inefficient algorithm (quadratic complexity) was found in Exiv2 versions v0.27.3 and earlier. The inefficient algorithm is triggered when Exiv2 is used to write metadata into a crafted image file. An attacker could potentially exploit the vulnerability to cause a denial of service, if they can trick the victim into running Exiv2 on a crafted image file. The bug is fixed in version v0.27.4. Note that this bug is only triggered when _writing_ the metadata, which is a less frequently used Exiv2 operation than _reading_ the metadata. For example, to trigger the bug in the Exiv2 command-line application, you need to add an extra command-line argument such as `rm`. | |||||

| abcm2ps v8.14.11 was discovered to contain an out-of-bounds read in the function calculate_beam at draw.c. | |||||
| CVE-2021-32062 | 2 Fedoraproject, Osgeo | 2 Fedora, Mapserver | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
| MapServer before 7.0.8, 7.1.x and 7.2.x before 7.2.3, 7.3.x and 7.4.x before 7.4.5, and 7.5.x and 7.6.x before 7.6.3 does not properly enforce the MS_MAP_NO_PATH and MS_MAP_PATTERN restrictions that are intended to control the locations from which a mapfile may be loaded (with MapServer CGI). | |||||
| CVE-2021-32056 | 2 Cyrus, Fedoraproject | 2 Imap, Fedora | 2024-11-21 | 4.0 MEDIUM | 4.3 MEDIUM |
| Cyrus IMAP before 3.2.7, and 3.3.x and 3.4.x before 3.4.1, allows remote authenticated users to bypass intended access restrictions on server annotations and consequently cause replication to stall. | |||||
| CVE-2021-32052 | 3 Djangoproject, Fedoraproject, Python | 3 Django, Fedora, Python | 2024-11-21 | 4.3 MEDIUM | 6.1 MEDIUM |
| In Django 2.2 before 2.2.22, 3.1 before 3.1.10, and 3.2 before 3.2.2 (with Python 3.9.5+), URLValidator does not prohibit newlines and tabs (unless the URLField form field is used). If an application uses values with newlines in an HTTP response, header injection can occur. Django itself is unaffected because HttpResponse prohibits newlines in HTTP headers. | |||||
| CVE-2021-31957 | 2 Fedoraproject, Microsoft | 4 Fedora, .net, .net Core and 1 more | 2024-11-21 | 5.0 MEDIUM | 5.9 MEDIUM |
| ASP.NET Core Denial of Service Vulnerability | |||||
| CVE-2021-31924 | 2 Fedoraproject, Yubico | 2 Fedora, Pam-u2f | 2024-11-21 | 4.6 MEDIUM | 6.8 MEDIUM |
| Yubico pam-u2f before 1.1.1 has a logic issue that, depending on the pam-u2f configuration and the application used, could lead to a local PIN bypass. This issue does not allow user presence (touch) or cryptographic signature verification to be bypassed, so an attacker would still need to physically possess and interact with the YubiKey or another enrolled authenticator. If pam-u2f is configured to require PIN authentication, and the application using pam-u2f allows the user to submit NULL as the PIN, pam-u2f will attempt to perform a FIDO2 authentication without PIN. If this authentication is successful, the PIN requirement is bypassed. | |||||
| CVE-2021-31829 | 3 Debian, Fedoraproject, Linux | 3 Debian Linux, Fedora, Linux Kernel | 2024-11-21 | 2.1 LOW | 5.5 MEDIUM |
| kernel/bpf/verifier.c in the Linux kernel through 5.12.1 performs undesirable speculative loads, leading to disclosure of stack content via side-channel attacks, aka CID-801c6058d14a. The specific concern is not protecting the BPF stack area against speculative loads. Also, the BPF stack can contain uninitialized data that might represent sensitive information previously operated on by the kernel. | |||||
